Control method and device based on depth sensing equipment

Abstract

A control method and device based on a depth sensing device, the method comprising the steps of: acquiring a hand movement trajectory collected by a depth sensor, determining a current target trajectory point set based on the hand movement trajectory, and the target trajectory point set Including the current trajectory point and the adjacent trajectory points of the current trajectory point; analyzing the target trajectory point set, determining the target trajectory characteristics of the target trajectory point set, and combining the target trajectory characteristics with the preset instructions The trajectory characteristic information of the trigger condition is compared and analyzed to determine whether it matches the corresponding command trigger condition; if it matches, a control command corresponding to the matched command trigger condition is issued. The scheme of the embodiment of the invention can meet the interactive control requirements of different motion trajectories, and is simple, stable, real-time, and easy for engineering application.

Description

technical field [0001] The invention relates to the field of interactive control, in particular to a control method based on depth sensing equipment and a control device based on depth sensing equipment. Background technique [0002] With the development of technology, it has become an important development direction of human-computer interaction to recognize gesture trajectories and realize interaction with hosts based on the recognized gesture trajectories. At present, there are three main ways to use gesture track recognition to realize interaction with the host: one is that the user wears special props, such as special gloves, to assist in recognition or improve the effect of recognizing gesture areas, but this method is inconvenient to use; the second It is to use an ordinary color camera to segment the image obtained by skin color, motion, texture and other information and track the human hand area to realize the recognition of dynamic gestures. However, this method is...

Problems solved by technology

[0003] However, the current human-computer interaction based on depth sensors usually realizes synchronous actions with the human body, or simple interactive control. In this interactive control, multiple complex steps such as gesture modeling and gesture segmentation are generally required. process, and different users will have speed differences, trajectory differences, proficiency differences, etc. when performing gestures, and it is impossible to achieve the control requirements of different motion trajectories.
